What's on display : eyes, arms, breasts, legs
Why it works : This pose taps into the animalistic side of human nature. The prowling model is the predator and we are her petrified prey.
What's important : This is an action pose! Alternating limb configuration, high/low shoulders, alternating high/low hips. Her head being raised shows a catlike alertness that's preferable to her head being lowered like a sniffing bloodhound. The above illustration shows her looking ahead, but she could (and probably should) be staring us down.
Twisted movement : If you're feeling extra adventurous, you needn't choose a one-way crawl. She could be changing direction while crawling, causing her torso to twist, and her hair and breasts to lurch back.
